IMPROVEMENT IN STEAM-TRAPS.

bpeeitication forming part of Letters Patent No. 43., [67, (lated June 14, 1864.

To all whom it may concern.-

Be it known that I, HUBERT Jos. Vans- SEN, of Luttich, (Liege,) in the Kingdom of Belgium, have invented a new and Improved Self-Acting Double Valve for SteaxnGylinders; and I do hereby declare that the following a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this s-peciiiea tion, in which- Figure l represents a longitudinal central section of my invention. Fig. 2 is a transverse vertical section ot' the same, taken in the line a; x, Fig. 1.

Similar letters of reference indicate like parts. u l

The object .of this invention is to t'ree a steam-cylinder from the water condensing in the same.

The invention consists in the employment or use of two valves so arranged in relation to each other and to a steameylinder that ifs-aid cylinder takes steam on one end by the action ot' the steam itselt' the valve communicating w'ti the said end ot' the cylinder will be closed and the other opened, and vice versa, and by these m'ans the condensed water accumulating on the exhausting end of the cylinder is allowed to escape without obstruction.

A r Apresents a T-shaped case, made of castirrn or'any other suitable 1naterial,and pro vided with Vthree outlets, t b c, one in the end of each of its shanks, as clearly shown in Fig. l ofthe drawings. The outlets a b communicate by suitable pipes with the opposite ends ot' a steam-cylinder, and the outlet c is con inected to a suitable wastepipe intended 4to to carry oit' the condensed water which is lia ble to accumulate in the cylinder.

The communication between the outlets a and c and b and c can be opened and closed by valves d e, which close up against the seats fg in the interior of the caseA. Said valves consist of simple disks, which tit easily on the central stem h, and are confined between the collar t' and nut j, a perforated tube, 7c, being placed between them, as clearly shown in Fig. 1. This tube tits nicely in the passage which terms the communication between the outlets a and b, and itis somewhat longer than the distance between the valve-seats f g. So that it projects beyond one or beyond the other of these seats. lf that end of the cylinder which communicates lwith the outlet b takes steam, the stem together with the valve and the tube l k, are thrown in the direction of the arrow marked thereon in Fig. 1, so that the valve c closes and the valve d opens, and the condensed water that may have accumulated in the exhaust end of the cylinder is free to escape through the outlet a, opening in the end ot' the tube k, next to the valve d, and wastepipe c. If the steam in the cylinder changes, the valves d c change automatically by the action of the steam,and the communication between. the outlet and waste-pipe c, is opened.

The amount ot' motion allowed to the tube 7c in its socket is regulated by the plug l,- which extends through a stung-box, m, into the chamber b, being prevented from dropping out spontaneously by the screw n, the point ot' which projects into a groove,o, turned in the plug. The lower or inner end of'this plug is iiat and catches in a groove, p, between the collar t' and head g of the stem 7L, and in Fig. lit is shown in such a 'position that its flat sides face the inner surfaces of the head and collar. In this position the tube k has its maximum amount ot' motion; but it' the plug l is turned so that the edges of its inner end bear against the inner surfaces ot the head and collar of the stem the motion allowed to the tube la is reduced to its minimum.

I do not wish to confine myself, however, to this precise arrangement ot the valves d e and tube 7c. Said valves may bc connected in va-rions ways and the perforated tube ,7c might be dispensed with altogether, the sole olijectr-i-v` being to connect the valves so that if one closes the other is compelled to open, and vice versa.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

The employment or use of two valves,A B, so arranged in relation to each other and to a steam-cylinder that it' said cylinder takes steam .on one end by the action of the steam itself the valve communicating with said end of the cylinder is closed and the other opened, and vice versa, and by these means'the condensed water accumulating on the exhausting end of the cylnder is allowed to escape without obstruction.

Dnrrn,

MARSHALL TALBOT.
